I just bought a 1989 245 with 153k and a manual trans. It runs perfectly and gets 28 mpg. The check engine light was on when I bought it and it displayed the 2-1-2 oxygen sensor code. When I erased the code it would come back after about 5 miles. The previous owner gave me a used oxygen sensor. I installed it and it still runs perfectly, & now it takes 50 - 500 miles for the light to come on and display 2-1-2. O2 sensor voltage is .568 and it fluctuates very little - goes to .570 if I rev it. Given how well it runs, I'm tempted to remove the check engine light bulb & forget it, but what would it take to fix it?
